It's lurking at the existing syntax definitions in the sub directory
'mcedit'. Once there was a chapter at the [F1]-help but I didn't found
it yet.
Provided as is/ happy hacking:
<mc-cfg-path>/mcedit/syntaxtest.syntax:
(This file have to be included in <mc-cfg-path>/mcedit/Syntax.)

At default context '=' is not a regular character. However
I changed that for context #1.

In context #2 braces '(' and ')' aren't regular characters.
So 'whole' takes them being delimiters. In context #3 they
are enlisted as regular characters, such that '111' don't
match.

IMHO,
even if you have regex, you cannot match the declaration of a C
function. Therefore it's more promising to highlight less than all.
Further effort made, should support migration of syntax highlighting
definitions to other editors.
